After the Texans’ 38-14 victory over the Titans on Sunday, some defensive players accused Tennessee tackle David Stewart of doing a Richie Incognito impersonation.
The Texans accused Stewart, a 6-7, 315-pound eight-year veteran, of playing dirty, including pulling linebacker Brooks Reed’s hair.

“I saw some things I’ve never seen before,” said defensive end Antonio Smith. “I saw him try to pull (Reed’s) hair out, tried to ride somebody’s back, which I thought was kind of funny, actually.”

After the opening win over Miami, Smith accused Incognito of trying to injure his ankle.

“He’s like Incognito,” outside linebacker Connor Barwin said of Stewart. “Everybody will say it — he’s a dirty player. He threw a punch at me. He threw a punch at Brooks.”

It got especially rough in the third quarter.

“One play, I saw J-Joe (cornerback Johnathan Joseph) making a tackle, and (Stewart) was around the pile, and he was trying to help (running back) Chris Johnson up,” said safety Danieal Manning. “J-Joe was down. He was kneeing J-Joe, and I said, ‘This guy’s crazy.’ ”

Reed compared the third quarter to a bar fight.

“You see it on film watching other teams play, so I knew it was inevitable,” Reed said.

Smith said Stewart’s behavior helped motivate the defense.

“When he started doing all that, that spark happened,” Smith said. “Everybody started making plays, so it kind of worked against them.”

Titans quarterback Matt Hasselbeck defended Stewart.

“I saw people punch (Stewart) in the face, and there was no (flag),” Hasselbeck said. “I don’t know what to say. I guess his reputation got him.”
